The AGA rules are the rules of the American Go Association. They use area scoring and situational superko, count eyes in seki, and forbid suicide. (They are therefore quite similar to Chinese rules.) Pass stones are used so that the score can be counted by methods usually used for territory scoring.

The French rules are essentially the same as AGA rules.
